I have the FAQ but no choice for Mass Update!
Not quite sure exactly what the question is, but I’m going to take a stab at it.
If you are looking to mass update contacts, run the contact search.
When you have your search completed, check the box at the top left of the search results. That will select all of the records.
Then, use the ‘Actions’ dropdown box.
Choose Mass Update Contacts
Then, edit the field you want to mass update and click save at the very bottom.
Hopefully that helps.
